KNCW ALL MEN BY THESE PRESENTS:

That I, E. F. LIGHT, of the city and county of Worcester, and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Journal-Boxes; and I do hereby declare 'that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming apart of this specication, in which- Figure 1 represents a perspective viewof my improved journal-box.

Figure 2 represents a longitudinal central section o n line A B, iig. 1, and

Figure 3 represents a cross-Section on line C D, same figure.

To enable those skilled inthe art towhieh my invention belongs to make and use the same, I will proceed todescribe it more in detail. A

In the drawings, the part marked A is the bottom ofthe bo'x, and has in thisinstance combined with it the stand or buck B, throughvwhich.aboltpasses to fasten the box in place. C is the cap, which is made tight on top, or without the usual oil-hole. It is chambered out upon the inside, and which chamber may be lled with some fibrousv material, a, if desired. The cap C is also curved or recessed out, as shown at b. The bottom` A ofthe boxmis chambered out upon'theA inside, as seen at c, and which chamber is connected with tbc end grooves d by a longitudinal groove,'e, in the bottom of the` box. The upper inner sides of the part A are chambered or cored ci? so as to forminclinedways ff from the end grooves d d to the chamber or recess c. The front part A is provided with ka projection, D, through which an oil-hole, g, passes, andcommunicates with the chamber c and groove e in the bottom of the part A. The oil-hole may be stopped to prevent the entrance of dust and dirt. Chamber c and-groove e may be filled with some fibrous material, h, as shown in the drawings.

The operation is as follows: Oil or some lubricatingsubstanee is turned into'the holeg, when' it descends and ills or partially lls the groove e, and-is taken up and brought in contact with the bearing of the shaft by means of the brous material z. Ifany ofthe lubricating Vsubstance is forced upon the ways ff, it runs back into the recess or chamber` c, and from thence to groove e again, while if any of the lubricating substance is forced vout at'the ends of the 'box itis caught by the grooves old and returned to the groove e. The operation is so perfect that one supply ofoil will last for months. The top ofthe projection D may be concaved out to facilitate and prevent the waste of oil when applied.

Having described my improved journal-box, what I claim therein as new, und of my invention, and desire to secure by Letters Patent, lis i 4 The combination of the projection D, oil-hole g, and grooves d d and e, and inclined ways ff, and chamber c, with the bottom part A of the journal-box for the purposes stated.
